WRENCH.

SPECIFICATION forming part of Letters Patent No. 398,989, dated March 5, 1889.

Application filed .Tune 30, 1888. Serial No. 278,'704. (Modelfl To ZZ whom it may cowerz:

Be it known that I, J OSEPH ToMLINsoN, of Folson, in the County of Sacremento and State of California have invented a new and useful Improvement in XVrenches, of which the following is a. specificetion.

My invention rclates to improvenents in that class ot' wrenches in which the jaws are pivoted within n treme or casing and are cansed to clamp the nut by e sliding handle engngng the rea-r ends of the said jaws.

The invention consists in the peeuliar construction and nrrangement of parts as here- :inztfter tully described, and pointed out in the claim.

Reference is to be had to the acconpenying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is n plan View of my improvement. Fig. 3 is nlongitndinnl section.

Refer'ing to the drewings by letter, A rep E resents the body of the wrench, which is coinposed of the top and bottom plates o a'. The bottom pla te, a', is provided at its rear end with the upwnrdly-projeeting flanges a which ere reduced to pass through epertures in the top pinte, a, and screw-threaded to receive the nnts 7), by which the said plates are Secured together. Between the pletes a a" are pivoted the icver-ja-ws B by means of I the 'bolts H, which pass through the said plates and are provided with the nuts 71 The forward ende of the lev'er-jaws B are constrncted in the form as shown at their forward ends to adapt them to receive a mit, and their rezuends are curved outwardly, as shown. In order that the lever-jaws B may be held open and ready for use, a spring, G, is interposed between the lever-jaws, with its ends engaging shoniders on the said leverj awsi For Operating the lever-jaws a sliding bar, C, provided with the head c, projects into the body, and to the said head c are attached the blocks E, which fit between the top and bottom plztes of the body and are notched or recessed to receive the rem' ends of the leverjews B. To the outer end of the ber C is detnchztbly Secured the handle D by means of the spring-pressed catch d, pivoted in the handle and enga ging a notch in the end of the ber C. By making the handle D removeble it may be taken off and the wreneh used With a bit-stock.

From the above-described Construction it will rendily be seen that the leVer-jaws, which are normally held open by the spring, may be closed upon ft nnt by moving the sliding har O inwerd, which movement Will force the inner ends of the lever-jttws outwnrd nd cause them to ola-nip the nut. For clamping the slidin g ber C, and the'eby holding the same in 9 is a sectional plan VGW} and the position to which ithas been moved, a

thnnb-screw, F, is passed through the top plote, a, so that its lower end will eng-age the said bar C. By this means the lover-j aws een be held locked in ai closed position when desired.

Having thus described my invention, what I claim, and desire to secure by Letters Petent, 15-

In a, Wrench, the combination, with the body portion A, of the leVer-jnws B, pivoted in and at the forward end of the body and having ontwardly-cufved renr ends, the spring G, in-

` terposed between the leVer-jaws for holding them open, the bar C, sliding within the body and provided with the head c, and the blocks E, Secured to the head c and recessed to receive the rear ends of the loveriews, substantially as described.
